How to 100% this game
Easy Achievement Guide
Minimum 3 play-through (better stay at one end of the map, remember to upgrade global skills in Main Menu after each run)
- 1st map: reach Wave 16 and fly away (as shotgun is strong, I mainly upgrade gun skills and buy Turrets as assistance);
- 2nd map: reach 30+ waves, buying Turrets, upgrading 3 levels for each of the 2 melee skills, remaining for Turret skills (very easy, can reach Level 50+ only relying on Turrets)
- 3rd map: reach Wave 16 and fly away, by buying and upgrading Turrets
2-3 hours to 100%.
